DETAILED DESCRIPTION

Hereinafter, example embodiments will be described in more detail with reference to the accompanying drawings.

In various embodiments, building management platforms such as a building management system include digital representations of physical spaces. For example, a building management system may include a digital twin of a building that represents the people, places, assets, and events within the building. In various embodiments, digital twins are generated during the construction of a building. For example, an architect may generate a building information model (BIM) that is used by builders to construct a building and service personnel to maintain the building. Additionally or alternatively, digital representations such as digital twins may be generated for existing buildings. For example, a building management system of an existing building may generate a digital representation of the building. However, it may be difficult to generate a digital representation of a building (new, existing, or otherwise). For example, manually identifying the assets in a building may be difficult and time consuming. As a further example, some sources of existing building data may not be easily translatable to a digital representation and may require manual transfer. Further, configuring the devices of the buildings/spaces to work properly with one another and with the building management system can be difficult and time-consuming as well. In general, it may be desirable to avoid manually generating digital representations of buildings (e.g., to reduce input errors, because of the amount of data to be input, etc.). Therefore, systems and methods of configuring a building management system are needed. Specifically, system and methods to facilitate ingesting building data, generating a digital representation, verifying and validating data in the digital representation, and deriving new information based on the digital representation are needed. Virtual representations, digital representations, smart entities, and digital twins are used interchangeably in the present disclosure; in other words, where the present disclosure refers to virtual representations or smart entities, it should be understood that the features discussed could be implemented using digital twins or any other digital counterpart (e.g., updated in real-time, near real-time, periodically, in response to events, or in any other fashion). Additionally, in various embodiments, the systems and methods of the present disclosure can utilize digital twins for higher-level entities (e.g., such as buildings or campuses that include or are otherwise related to particular spaces, assets such as building equipment, people, and/or events) and/or for lower-level entities, such as digital twins of particular spaces (e.g., rooms, floors, etc.), people, assets (e.g., particular pieces of building equipment or groups of building equipment), and events. All such implementations are contemplated within the scope of the present disclosure.

One solution may include a building management platform such as a cloud building management platform. The building management platform may automatically tag data points associated with a digital representation of a building (e.g., using context data associated with the data points, etc.). In various embodiments, the tags associate one or more data points with one or more entities such as building equipment, building spaces, people, and/or events. In various embodiments, the building management platform identifies data points for manual review. For example, the building management platform may identify a data point having a low confidence tag (e.g., a tag with a low probability of being valid, etc.) and may surface the data point to a user along with a suggested tag for the data point. In various embodiments, data points refer to one or more data elements (e.g., measurements, etc.) associated with an entity. For example, a data point may include a sensor measurement generated by a temperature sensor. As another example, a data point may include timeseries sensor measurements representing temperature measurements generated by a temperature sensor over the course of the temperature sensor's operation.

In various embodiments, the building management platform executes one or more models (e.g., machine learning models, linear regression models, etc.) to perform the various operations described herein. In various embodiments, the building management platform updates the one or more models based on user feedback. For example, the building management platform may surface a data point to a user as potentially having an incorrect tag, the user may verify that the tag is correct, and the building management platform may update a model for predicting the validity of data points based on the user feedback (e.g., such that the building management platform doesn't surface similar data points as potentially having an incorrect tag in the future, etc.).

In various embodiments, the building management platform trains a machine learning algorithm on historical information to generate tag suggestions for data points. For example, the building management platform may retrieve historical operating information for a building, may train a machine learning algorithm using the historical operating information, and may execute the trained machine learning algorithm on context data associated with a data point to generate a suggested tag for the data point. In various embodiments, the building management platform analyzes descriptive information describing an entity to extract semantic information describing one or more attributes of the entity. For example, the building management platform may execute a natural language processing (NLP) algorithm on descriptive information associated with an embedded building controller to extract a name and/or identifier for the building controller. In various embodiments, the building management platform performs signal analysis on operational data associated with a data point to determine a validity of a tag associated with the data point. For example, the building management platform may analyze thermostat control data and temperature measurements to verify a tag linking the thermostat to a particular space (e.g., by identifying a change in a temperature of the space corresponding to a change in temperature setpoint included in the control data, etc.).

In various embodiments, the building management platform displays a confidence metric describing a likelihood that a suggested tag is valid to a user. For example, the building management platform may generate a suggested tag, may generate a confidence metric associated with the suggested tag (e.g., where a higher confidence level may indicate that the building management platform has more data verifying the suggested tag, etc.), and may display the confidence metric along with the suggested tag to a user (e.g., thereby enabling the user to investigate and/or override tags having low confidences, etc.). In various embodiments, a user may manually adjust information associated with a suggested tag generated by the building management platform. For example, the building management platform may generate a suggested tag associated with a first space and a user may adjust the tag to be associated with a second space. In various embodiments, a user may verify a suggested tag generated by the building management platform. For example, the building management platform may generate a suggested tag, display the suggested tag to a user, and the user may verify that the suggested tag is correct. In some embodiments, the building management platform may update a confidence metric based on user feedback regarding a suggested tag. For example, the building management platform may increase the value of a confidence metric associated with a tag based on a user verifying the tag (e.g., confirming the tag is correct, etc.). In some embodiments, the building management platform generates a data health metric describing a validity of data associated with a building (e.g., how accurate a number of tags in a digital representation of a building are, etc.) based on one or more confidence metrics (e.g., by combining the confidence metrics, etc.). In various embodiments, the building management platform may identify one or more missing data points and/or one or more missing data sources (e.g., missing data that impacts a data health metric, etc.). For example, the building management platform may determine that a digital representation is missing temperature data for a particular floor of a building and may generate a suggestion to obtain the missing temperature data (e.g., by using a substitute/proxy for the data, by modeling the data, etc.).

In various embodiments, the building management platform may dynamically generate a suggested tag. For example, the building management platform may dynamically control an environmental variable of a building, monitor sensor measurements, and generate a suggested tag based on the monitored sensor measurements. Additionally or alternatively, the building management platform may perform a similar process (e.g., dynamically controlling an environmental variable, etc.) to validate one or more tags.

In various embodiments, the building management platform may identify one or more substitutes for unreliable data points. For example, the building management platform may identify a second data point that is similar to a first data point, and may use information from the second data point to control a piece of building equipment associated with the first data point. In various embodiments, the building management platform performs one or more actions in response to identifying a data point as unreliable (e.g., having a low confidence metric, etc.). For example, the building management platform may suppress one or more alarms associated with an unreliable data point.

In various embodiments, the building management platform may perform one or more actions in response to identifying an anomaly associated with a data point. For example, the building management platform may determine whether the anomaly relates to an incorrect tag, a device fault, an unexpected configuration, and/or a change in at least one of a space of a building or a use of a space. Additionally or alternatively, the building management platform may automatically update incorrect tags and/or automatically update a device configuration associated with a data point to address an anomaly. In various embodiments, the building management platform may identify a drift condition associated with a data point. For example, the building management platform may perform signal analysis on temperature data to identify whether the temperature data transitions from an expected range to an unexpected range. As another example, the building management platform may compute a covariance between a number of data points and may identify a drift condition based on a change in the covariance (e.g., such as when two historically correlated equipment measurements begin to diverge, etc.).

In various embodiments, the building management platform may analyze historical operating data to identify an anomaly. For example, the building management platform may compare operating data for a first data point to operating data for a second related data point to identify whether the first and second data points diverge in operation. In some embodiments, the building management platform generates a trend for one or more data points. For example, the building management platform may analyze historical temperature measurements associated with a room to identify a trend in the temperature setpoints associated with the room. In various embodiments, the building management platform generates a root cause (e.g., a reason an event occurred, etc.) associated with detected anomalies.

In various embodiments, the building management platform generates suggestions to modify one or more attributes for triggering a fault. For example, the building management platform may identify a root cause of a high temperature fault as a temperature threshold value that is set incorrectly and may generate a suggestion to update the temperature threshold value to a different value. In various embodiments, the building management platform automates the process of generating and deploying a digital representation of a building, thereby reducing or eliminating a need for manual intervention. In various embodiments, the building management platform may ingest and interpret external data sources (e.g., BIM data, enterprise management data, personnel data, etc.), extract semantic information from external data sources, dynamically determine configuration information, automatically enrich digital representations with derived information, and/or generate digital representations for spaces. In some embodiments, the digital representations may be used to configuration and/or control building equipment and/or other assets contained in buildings/spaces, and may significantly lower the time and expense of commissioning and configuring new buildings and spaces.

Referring now to FIGS. 1A-1B, a block diagram of a smart building environment 100 is shown, according to an exemplary embodiment. Smart building environment 100 is shown to include cloud building management platform 140. In various embodiments, cloud building management platform 140 facilitates rapid commissioning and/or configuration of building models. Cloud building management platform 140 may be configured to collect information from a variety of different data sources. Cloud management platform 140 may create digital representations, referred to as “digital twins,” of physical spaces, equipment, people, and/or events based on the collected information. In various embodiments, the digital representations are stored in an entity graph. In brief overview, an entity graph is a data structure representing entities (e.g., spaces, equipment, people, events, etc.) and relationships between the entities. In various embodiments, the entity graph data structure facilitates advanced artificial intelligence and machine learning associated with the entities. In various embodiments, entities within the entity graph data structure include or are associated with “agents,” or software entities configured to take actions with respect to the digital twins/real world entities with which they are associated. In some implementations, the agents may be configured to implement artificial intelligence/machine learning methodologies. The agents may be configured to facilitate communication and collection of information between the varieties of different data sources. Each of the data sources may be implemented as, include, or otherwise use respective agents for facilitating communication amongst or between the data sources and cloud building management platform 140.

In various embodiments, cloud building management platform 140 collects data from buildings 10. For example, cloud building management platform 140 may collect data from buildings 10 such as a school, a hospital, a factory, an office building, and/or the like. It should be understood that the present disclosure is not limited to the number or types of buildings 10 shown in FIG. 1B. As new devices/components/spaces/buildings/events/control loops are added or otherwise incorporated into smart building environment 100, new digital representations (and associated agents, etc.) may be dynamically generated and incorporated into the entity graph data structure. Moreover, it should be understood that while cloud building management platform 140 is described in relation to a cloud/distributed processing system, the functionality of cloud building management platform 140 may be implemented locally. For example, cloud building management platform 140 may be implemented as an off-premises server, set of off-premises servers, and/or one or more on-premises servers. In some implementations, the features of cloud building management platform 140 and/or BMS 102 may be combined in one system. All such permutations are within the scope of the present disclosure.

In some embodiments, entities 12 include equipment such as inventory, assets, furniture, vehicles, building components, devices, and the like. For example, entities 12 may include devices such as internet of things (IoT) devices. IoT devices may include any of a variety of physical devices, sensors, actuators, electronics, vehicles, home appliances, and/or other items capable of communicating data over an electronic network (e.g., smart lights, smart appliances, smart home hub devices, etc.). In some embodiments, entities 12 include events such as meetings, fault indications, alarms, and the like. In various embodiments, cloud building management platform 140 receives information associated with buildings 10 and/or entities 12 and generates an entity graph based on the received information. The entity graph may include digital twins that are digital representations of real world spaces, equipment, people, events, and/or the like. Entity graphs are described in greater detail below with reference to FIG. 21.

Smart building environment 100 may include building management system (BMS) 102. In various embodiments, BMS 102 communicates with cloud building management platform 140 to facilitate management and control of buildings 10 and/or the various operations described herein. BMS 102 may be configured to control, monitor, and/or manage equipment in or around a building or building area (e.g., such as buildings 10, etc.). For example, BMS 102 may include a HVAC system, a security system, a lighting system, a fire alerting system, and any other system that is capable of managing building functions or devices, or any combination thereof. Further, each of the systems may include sensors and other devices (e.g., IoT devices) for the proper operation, maintenance, monitoring, and the like of the respective systems. In some embodiments, each of buildings 10 is associated with a BMS 102. Additionally or alternatively, a single BMS 102 may manage multiple buildings 10. For example, a first BMS 102 may manage a first building 10, a second BMS 102 may manage a second building 10, and a third BMS 102 may manage the first and second buildings 10 (e.g., via the first and second BMS 102, in a master-slave configuration, etc.), as well as a third building 10.

For example, building subsystems 120 may additionally or alternatively include a refrigeration subsystem, an advertising or signage subsystem, a cooking subsystem, a vending subsystem, a printer or copy service subsystem, or any other type of building subsystem that uses controllable equipment and/or sensors to monitor or control a building 10. In some embodiment each of buildings 10 includes building subsystems 120. Additionally or alternatively, multiple buildings 10 may share at least some of building subsystems 120.

Each of building subsystems 120 may include any number of devices (e.g., IoT devices), sensors, controllers, and connections to facilitate functions and control activities.

Communications interface 104 may facilitate communications between BMS 102 and external systems/applications (e.g., cloud building management platform 140, remote systems and applications 30, client devices 40, third party services 50, building subsystems 120, etc.). Communications interface 104 may be or include wired or wireless communications interfaces (e.g., jacks, antennas, transmitters, receivers, transceivers, wire terminals, etc.) for conducting data communications within smart building environment 100 and/or with other external systems or devices. In various embodiments, communications via communications interface 104 is direct (e.g., local wired or wireless communications). Additionally or alternatively, communications via communications interface 104 may be via network 20 (e.g., a WAN, the Internet, a cellular network, etc.). For example, cloud building management platform 140 may communicate with BMS 102 using a wired connection and may communicate with client devices 40 (e.g., via BMS 102, etc.) using a cellular connection (e.g., a 4G or 5G access point/small cell base station, etc.).

According to some embodiments, memory 110 is communicably connected to processor 108 via processing circuit 106 and includes computer code for executing (e.g., by processing circuit 106 and/or processor 108) one or more of the operations described herein.

In some embodiments, BMS 102 and/or cloud building management platform 140 are implemented within a single computer (e.g., one server, one housing, etc.). In various other embodiments BMS 102 and/or cloud building management platform 140 are distributed across multiple servers or computers (e.g., that can exist in distributed locations). In some embodiments, functions of BMS 102 and/or cloud building management platform 140 are implemented as agents. For example, BMS 102 may include a fault detection agent configured to analyze building data and detect faults associated with building components.

In various embodiments, machine learning models database 190 stores machine learning models trained by cloud building management platform 140. For example, cloud building management platform 140 may train a neural network using historical operating data to predict HVAC faults and may store the trained neural network in machine learning models database 190.

Referring now to FIG. 2, method 200 for automatically tagging a number of data points is shown, according to an exemplary embodiment. In various embodiments, cloud building management platform 140 performs method 200. Additionally or alternatively, method 200 may be performed by another system such as building management system 102. At step 210, cloud building management platform may identify a first number of data points in a building. In some embodiments, step 210 includes performing semantic extraction on one or more elements such as strings to extract a number of data points from the elements. For example, cloud building management platform 140 may execute a GPT-2 model on text strings to identify one or more data points representing devices from within the text strings.

At step 220, cloud building management platform 140 may automatically tag at least a portion of the first number of data points with one or more first tags using context data extracted from and/or associated with the first number of data points. In various embodiments, the one or more first tags associate the portion of the first number of data points with one or more entities. In various embodiments, the one or more entities include at least one of building equipment, building spaces, people, and/or events. In various embodiments, the context data includes information related to similar data points and/or entities that interact with the first number of data points. For example, cloud building management platform 140 may retrieve a number of data points that are related to a first data point (e.g., through a relationship tag, etc.) and may use the number of data points to generate a location tag for the first data point (e.g., a tag associating the first data point with a space such as a room, etc.).

In various embodiments, step 220 includes generating a tag using machine learning. For example, cloud building management platform 140 may execute an AI model on an identifier of a data point to determine one or more tags relating to the data point. In some embodiments, step 220 includes perturbing one or more attributes associated with a data point to validate the one or more first tags. For example, cloud building management platform 140 may dynamically control an environmental variable associated with a data point to determine whether the data point behaves as expected given a change in the environmental variable to validate the data point. As another example, cloud building management platform 140 may change a temperature setpoint associated with a room, receive feedback from one or more individuals located in the room (e.g., feedback regarding the temperature, etc.), and may determine whether a tag for a temperature controller indicating that the temperature controller relates to the room is valid.

At step 230, cloud building management platform 140 may identify at least one of the first plurality of data points for manual review. For example, cloud building management platform 140 may identify a data point having a low confidence metric (e.g., low confidence that the data point is correctly tagged, etc.) and may surface the data point for manual review by a user. In various embodiments, step 230 includes identifying a data point for manual review using signal analysis. For example, cloud building management platform 140 may compare sensor values from an AHU to expected sensor values generated by an machine learning model to determine whether the sensor values deviate from the expected sensor values, thereby indicating that the AHU may be incorrectly configured (e.g., tagged incorrectly, etc.). In some embodiments, step 230 includes identifying a tag for manual review. For example, cloud building management platform 140 may identify a tag based on a confidence metric associated with the tag falling outside an acceptable range. For example, a confidence metric for a tag of a data point may be at a 20% level and cloud building management platform 140 may identify the tag as falling below a 40% confidence metric threshold. In various embodiments, cloud building management platform 140 identifies one or more data points and/or tags for manual review based on a confidence metric associated with the data points and/or tags. In various embodiments, cloud building management platform 140 generates confidence metrics for data points and/or tags using context data associated with the data points and/or tags. For example, cloud building management platform 140 may assign a low confidence metric value to a data point that frequently deviates from expected behavior (e.g., based on a model for predicting the behavior of the data point, etc.). In various embodiments, cloud building management platform 140 displays a confidence metric alongside a data point. For example, cloud building management platform 140 may identify a data point for manual review and may display a confidence metric associated with the data point when displaying a suggestion to review the data point to a user.

At step 240, cloud building management platform 140 may generate one or more suggested tags for the at least one data point. For example, cloud building management platform 140 may identify from a name of the data point a building the data point is associated with and may generate a suggested tag to associate the data point with the building. In various embodiments, the one or more suggested tags associate a data point with an entity such as a building space. In various embodiments, step 240 includes executing a machine learning model to generate the one or more suggested tags. For example, cloud building management platform 140 may execute an AI model using an identifier associated with a data point to generate a suggested tag for the data point. In some embodiments, step 240 includes dynamically controlling one or more environmental variables to determine a suggested tag. For example, cloud building management platform 140 may control an environmental variable for a space, may observe that sensor measurements associated with a data point reflect a change in the environmental variable, and may generate a suggestion to tag the data point as being associated with the space based on the observation. In some embodiments, the one or more suggested tags include a new tag. For example, a data point may be missing one or more tags and cloud building management platform 140 may generate one or more tags to fill the missing one or more tags. Additionally or alternatively, the one or more suggested tags may include an adjustment to an existing tag. For example, cloud building management platform 140 may generate a suggestion to change an existing tag from associating a HVAC component with a first space to associating the HVAC component with a second space. In some embodiments, step 240 includes surfacing the one or more suggested tags for manual review (e.g., displaying a GUI element to a user, etc.).

At step 250, cloud building management platform 140 may receive feedback from the manual review. For example, cloud building management platform 140 may receive an indication that a user has confirmed a suggested tag (e.g., by a user selecting a “confirmation” option in a GUI, etc.). In various embodiments, step 250 includes receiving a manual adjustment of a suggested tag from a user. For example, cloud building management platform 140 may suggest a tag having a first attribute to a user and may receive feedback from the user indicating that the tag should have a second attribute instead of the first attribute (e.g., associate a piece of equipment with a second building space rather than a first building space, etc.). In some embodiments, step 250 includes receiving a user validation of the one or more suggested tags. For example, a user may confirm that a suggested tag is correct. In various embodiments, step 250 may include increasing a confidence metric associated with a data point and/or a tag based on the received feedback. For example, cloud building management platform 140 may increase a confidence metric value associated with a data point in response to receiving a user confirmation that a tag of the data point is valid. In various embodiments, step 250 includes updating a machine learning model based on the received feedback. For example, a machine learning model may determine that data points having a first name are generally associated with equipment of a first type, cloud building management platform 140 may receive user feedback indicating that a data point having the first name is associated with equipment of a second type and may update the machine learning model based on the user feedback (e.g., such that a confidence of the machine learning model associating data points having the first name with equipment of a first type is reduced, etc.).

At step 260, cloud building management platform 140 may receive a second number of data points in the building. For example, cloud building management platform 140 may identify one or more data points based on a machine learning model that was updated based on user feedback during step 250 (e.g., where updating the machine learning model caused a number of confidence metrics associated with previously tagged data points to fall below a threshold, etc.). At step 270, cloud building management platform 140 may automatically tag at least a portion of the second number of data points with one or more second tags using the feedback from the manual review. For example, cloud building management platform 140 may receive feedback indicating that equipment that was previously tagged as being located in a first building is actually located in a second building and may update a number of tags associated with data points to reflect that the data points are associated with the second building instead of the first building. In various embodiments, step 270 includes updating one or more data points associated with a different building. For example, cloud building management platform 140 may perform method 200 for a first building and may use feedback received during execution of method 200 for the first building to update one or more tags for a second building (e.g., generate suggested tags for the second building based on the feedback received for the first building, etc.).

In some embodiments, method 200 includes identifying unreliable data and/or determining a substitute/proxy for unreliable data. For example, cloud building management platform 140 may detect a drift condition associated with a piece of equipment (e.g., using a fault detection and diagnosis system, etc.), may identity a root cause of the drift condition (e.g., using a machine learning model trained on historical operating data, using a rules engine, etc.), and may identify a substitute for sensor data associated with the piece of equipment based on the identified root cause. In some embodiments, identifying unreliable data includes analyzing a confidence metric and/or data health metric associated with an entity. For example, cloud building management platform 140 may identify that energy consumption data associated with a first building may be unreliable based on the first building having a low data health metric value. In some embodiments, method 200 includes analyzing a covariance between one or more entities. For example, cloud building management platform 140 may determine that a first piece of building equipment and a second piece of building equipment that historically have high covariance values suddenly became decoupled (e.g., are no longer correlated, etc.) and may identify the change a drift condition.

In some embodiments, method 200 includes suppressing one or more alarms. For example, cloud building management platform 140 may receive user feedback (e.g., during step 250, etc.) indicating that a piece of building equipment has been configured improperly (e.g., has an incorrect tag, etc.) and may suppress a number of alarms associated with the piece of building equipment because the alarms were based on the incorrect configuration of the piece of building equipment. In some embodiments, method 200 includes identifying an anomaly associated with an entity and/or determining a cause of the anomaly. For example, cloud building management platform 140 may identify a change in a trend associated with temperature measurements of a room (e.g., where the temperature measurements deviate from historical temperature measurements, etc.) and may determine a root cause of the change in the trend (e.g., a malfunctioning damper, an incorrectly configured temperature controller, etc.). In various embodiments, cloud building management platform 140 may automatically fix identified anomalies. For example, cloud building management platform 140 may automatically correct an incorrectly configured temperature controller that is causing a temperature anomaly in a room. Additionally or alternatively, cloud building management platform 140 may surface the anomalies to a user (e.g., via a GUI, etc.).

In some embodiments, method 200 includes adjusting one or more rules associated with a building management system. For example, a building management system may include a fault detection and diagnosis (FDD) system configured to generate alarms based on equipment faults and cloud building management platform 140 may dynamically adjust one or more rules used by the FDD system to generate alarms. In some embodiments, method 200 includes generating one or more templates. For example, cloud building management platform 140 may generate an equipment template for a piece of HVAC equipment specifying one or more attributes of the HVAC equipment (e.g., tags associated with the HVAC equipment, normal operating ranges of the HVAC equipment, an operational schedule for the HVAC equipment, etc.).

Referring now to FIG. 3, step 210 is shown in greater detail, according to an exemplary embodiment. At step 212, cloud building management platform 140 may retrieve descriptive data describing an entity. For example, cloud building management platform 140 may perform a “BACnet scan” to retrieve identifiers associated with one or more building controllers located in a building. At step 214, cloud building management platform 140 may perform semantic extraction on the descriptive data to identify one or more attributes of the entity. For example, cloud building management platform 140 may execute a NLP algorithm on an equipment identifier to determine a portion of a building that a piece of equipment is associated with. At step 216, cloud building management platform 140 may generate one or more data points based on the one or more attributes. For example, cloud building management platform 140 may generate a data structure, within a graph data structure representing a digital twin of a building, representing a data point associated with a thermostat based on identifying a thermostat identifier from within the descriptive data. As another example, cloud building management platform 140 may generate a data point representing an occupancy sensor and associate the data point with a room (e.g., via a tag, etc.) based on identifying a room identifier in the descriptive data. In various embodiments, step 216 occurs in response to determining that no existing data point relates to the entity (e.g., therefore a new data point must be created, etc.). At step 218, cloud building management platform 140 may identify one or more data points based on the one or more attributes. For example, cloud building management platform 140 may perform a lookup within a graph data structure using an identifier identified during step 214 to retrieve a data point associated with the entity. In various embodiments, step 218 includes identifying one or more existing data points associated with a building. For example, cloud building management platform 140 may identify an equipment identifier from within the descriptive data and may use the equipment identifier to retrieve a data point associated with the equipment identifier from within a building model such as a digital twin.

Referring now to FIG. 4, step 220 is shown in greater detail, according to an exemplary embodiment. At step 410, cloud building management platform 140 may receive one or more data points. For example, cloud building management platform 140 may receive a data point from a user (e.g., via selection of the data point using a GUI, etc.). At step 420, cloud building management platform 140 may execute a machine learning model on context data associated with the one or more data points to generate a tag. For example, cloud building management platform 140 may execute a GPT-2 model trained using data mapping data points to their associated tags to generate a tag for the one or more data points. In some embodiments, step 420 includes generating multiple tags. In various embodiments, the context data includes information such as a location of a data point, a piece of equipment associated with a data point, historical operating parameters associated with a data point, an identifier of the data point, and/or the like. In some embodiments, the context data includes a confidence metric (e.g., a confidence metric associated with a likelihood that an existing tag of a data point is valid, etc.). In some embodiments, step 420 includes generating a confidence metric for the generated tag (e.g., based on the machine learning model, etc.).

At step 430, cloud building management platform 140 may compare a confidence metric associated with the tag to a threshold. For example, cloud building management platform 140 may compare a tag having a confidence metric value of 30% to a threshold. In some embodiments, the threshold is static (e.g., a fixed value, etc.). Additionally or alternatively, the confidence metric may be dynamic (e.g., change based on a type of data point, or type of equipment associated with the data point, etc.). At step 434, cloud building management platform 140 may surface the tag for manual review. For example, cloud building management platform 140 may surface a tag generated during step 420 for manual review in response to determining that the tag has a confidence metric value that is below a threshold value. In various embodiments, step 434 includes displaying a graphical user interface (GUI) to a user. GUIs relating to data points and/or tags are described in greater detail below.

At step 432, cloud building management platform 140 may automatically tag at least one of the one or more data points with the tag based on the comparison. For example, cloud building management platform 140 may automatically tag a data point with the tag generated by the machine learning model in response to determining that a confidence metric associated with the tag exceeds a threshold value. At step 440, cloud building management platform 140 may dynamically control an environmental variable of the building. For example, cloud building management platform 140 may override a temperature setpoint for a space to change a temperature of the space. In various embodiments, the environmental variable is associated with the one or more data points and/or the tag. For example, the one or more data points may include a data point associated with a thermostat in a space and step 440 may include adjusting a temperature of the space (e.g., by controlling HVAC equipment, etc.).

At step 450, cloud building management platform 140 may monitor sensor measurements of sensors associated with the building. For example, cloud building management platform 140 may monitor a temperature sensor associated with a room (e.g., located within the room, etc.). At step 460, cloud building management platform 140 may determine whether the sensor measurements align with expected behavior. For example, cloud building management platform 140 may compare an expected covariance of the sensor measurements and the change in the environmental variable to an actual covariance of the sensor measurements and the change in the environmental variable. At step 470 (YES), cloud building management platform 140 may determine the tag is valid. For example, cloud building management platform 140 may automatically close the blinds in a room, may measure (e.g., via a camera, etc.) an amount of ambient light in the room, and may determine whether a controller for the blinds is mapped to the correct room within a building model based on observing that the amount of ambient light in the room decreases in response to the blinds being closed. At step 480 (NO), cloud building management platform 140 may determine the tag is not valid. For example, cloud building management platform 140 may automatically disconnect a router from an Internet connection, may monitor user devices located in an area served by the router to determine whether they lose their Internet connection, and may determine that the router is incorrectly configured (e.g., has an incorrect tag associating the router with the location, etc.) based on observing that none of the user devices lose their Internet connection as would be expected.

Referring now to FIG. 5, step 230 is shown in greater detail, according to an exemplary embodiment. At step 232, cloud building management platform 140 may receive one or more data points. At step 234, cloud building management platform 140 may retrieve one or more confidence metrics, each of the one or more confidence metrics associated with at least one of a tag of the one or more data points or a data point of the one or more data points. For example, cloud building management platform 140 may retrieve a confidence metric describing a likelihood (e.g., expressed as a percentage, etc.) that a HVAC damper is configured correctly (e.g., is tagged as serving the correct building space, etc.).

At step 236, cloud building management platform 140 may compare each of the one or more confidence metrics to a threshold. For example, cloud building management platform 140 may compare a confidence metric to a threshold range representing an acceptable range (e.g., a range at which a tag is more likely than not to be correct, etc.). In some embodiments, step 236 includes comparing the confidence metric to a number of ranges. At step 238, cloud building management platform 140 may select at least one of the one or more data points for manual review based on the comparison. For example, cloud building management platform 140 may determine that a number of data points having associated confidence metrics that are below a 50% threshold should be manually reviewed for accuracy.

Referring now to FIG. 6, step 240 is shown in greater detail, according to an exemplary embodiment. At step 610, cloud building management platform 140 may receive one or more data points. At step 620, cloud building management platform 140 may execute a machine learning model on context data associated with the one or more data points to generate a suggested tag. For example, cloud building management platform 140 may execute an Al classifier on operational data associated with the one or more data points to generate a suggested tag describing a type of equipment the one or more data points are associated with. Additionally or alternatively, at step 630, cloud building management platform 140 may dynamically control an environmental variable of the building. For example, cloud building management platform 140 may automatically turn off lights in a particular space of a building associated with the one or more data points. At step 640, cloud building management platform 140 may monitor sensor measurements of sensors associated with the building. For example, cloud building management platform 140 may monitor a light sensor positioned in a room.

Additionally or alternatively, at step 650, cloud building management platform 140 may identify one or more entities that are correctly tagged. For example, cloud building management platform 140 may retrieve one or more data points that a user has previously validated (e.g., validating one or more tags associated with the one or more data points, etc.). As another example, cloud building management platform 140 may retrieve a data point having a high confidence metric value (e.g., 90%, 100%, etc.). At step 660, cloud building management platform 140 may modify operation of the one or more entities. For example, cloud building management platform may retrieve a data structure representing a thermostat that is correctly tagged (e.g., tagged as controlling a particular component of an HVAC system, etc.) and may modify a temperature setpoint associated with the thermostat. At step 670, cloud building management platform 140 may monitor sensor measurements associated with a data point that is effected by the modified operation. For example, cloud building management platform 140 may monitor a temperature sensor in a room effected by a change in temperature setpoint.

At step 680, cloud building management platform 140 may generate a suggested tag based on the monitored sensor measurements. For example, cloud building management platform 140 may generate a suggestion to tag a light controller as being associated with a particular room in response to observing a correlation between light measurements in the room and a command to change lighting conditions in the room. As another example, cloud building management platform 140 may generate a suggestion to adjust a tag for a temperature sensor from being associated with a first room to being associated with a second room in response to measuring a correlation between a change in a temperature setpoint associated with a thermostat that is known to be correctly tagged as relating to the first room and temperature measurements associated with the temperature sensor (e.g., where the temperature measurements do not reflect the change in the temperature setpoint, etc.).

Referring now to FIG. 7, step 250 is shown in greater detail, according to an exemplary embodiment. At step 252, cloud building management platform 140 may receive feedback from one or more users regarding one or more suggested tags. For example, cloud building management platform 140 may receive a user validation of a suggested tag. As another example, cloud building management platform 140 may receive an adjustment of a suggested tag from a user (e.g., a user changing a tag associating a piece of HVAC equipment with a first space to associating the piece of HVAC equipment with a second space, etc.). At step 254, cloud building management platform 140 may update a confidence metric describing a likelihood that a tag of the one or more suggested tags is valid based on the feedback. For example, cloud building management platform 140 may increase a confidence metric value associated with the tag in response to receiving user feedback verifying the tag. As another example, cloud building management platform 140 may decrease a confidence metric value associated with a tag in response to a user indicating that the suggested tag is not valid.

At step 256, cloud building management platform 140 may update a building health metric based on the updated confidence metric. For example, cloud building management platform 140 may update a building health metric describing an aggregate level of confidence in the likelihood that tags in a building model relating to a building are correct. In various embodiments, step 256 includes computing an aggregate value using a number of confidence metrics associated with data points and/or tags in a building model. For example, cloud building management platform 140 may aggregate 10,000 confidence metrics associated with data points included in a building model for an office building. At step 258, cloud building management platform 140 may update a machine learning model used to generate a tag of the one or more suggested tags based on the feedback. For example, cloud building management platform 140 may at least partially retrain a machine learning model using the feedback. As another example, cloud building management platform 140 may update one or more weights associated with nodes in an Al neural network based on the feedback.

Referring now to FIG. 8, step 270 is shown in greater detail, according to an exemplary embodiment. At step 272, cloud building management platform 140 may receive feedback from one or more users regarding one or more suggested tags associated with a building. For example, cloud building management platform 140 may receive user feedback validating a suggested tag (e.g., confirming the suggested tag is correct, etc.). At step 274, cloud building management platform 140 may identify a data analytics model for a different building other than the building. For example, cloud building management platform 140 may retrieve a building model relating to a different building that is similar to the building (e.g., sharing one or more characteristics such as size, location, use, etc.). In some embodiments, cloud building management platform 140 identifies the data analytics model from within building model database 180.

At step 276, cloud building management platform 140 may identify one or more data points for the different building that are similar to the one or more data points of the building. For example, cloud building management platform 140 may retrieve, from the data analytics model for the different building, one or more data points associated with a thermostat that is of a similar type as a thermostat in the building. At step 278, cloud building management platform 140 may update the one or more data points for the different building based on at least one of the one or more data points of the building or the feedback. For example, cloud building management platform 140 may receive feedback indicating that HVAC equipment that was previously tagged as being of a first type is actually of a second type and may update the one or more data points for the different building based on the feedback. As another example, cloud building management platform 140 may determine that data points associated with a first type of equipment are tagged as relating to a first supplier in a first building model and may update a second building model to align the data points of the second building model that are associated with the first type of equipment to reflect the relation to the first supplier.

Referring now to FIG. 9, method 900 for generating a suggestion relating to one or more data points is shown, according to an exemplary embodiment. In various embodiments, cloud building management platform 140 performs method 900. Additionally or alternatively, any other system such as building management system 102 may perform method 900. At step 910, cloud building management platform 140 may receive sensor information associated with a first data point of a first type. For example, cloud building management platform 140 may receive temperature sensor measurements associated with a data point relating to a thermostat of a first model. At step 920, cloud building management platform 140 may compare the received sensor information to expected sensor information associated with a data point of the first type. For example, cloud building management platform 140 may compare the received temperature measurements associated with a space to expected temperature measurements associated with the space generated by a machine learning model trained on historical temperature data for the space. In some embodiments, the expected sensor information includes a measure of variance and/or statistical spread. For example, cloud building management platform 140 may compare the received sensor information to a mean value associated with similar sensor information in a historical database to determine how many standard deviations from the mean the received sensor information is.

At step 930, cloud building management platform 140 may determine that the first data point is unreliable based on the comparison. For example, cloud building management platform 140 may determine that the received sensor information deviates by a threshold amount (e.g., a threshold covariance, etc.), thereby indicating that the first data point is unreliable. In some embodiments, step 930 includes comparing a measure of variance and/or statistical spread associated with the received sensor information to a threshold value for statistical spread such as a threshold number of standard deviations.

At step 940, cloud building management platform 140 may identify a second data point as a substitute for the first data point. For example, cloud building management platform 140 may identify a second temperature sensor that is in the same room as a first temperature sensor that may serve as a substitute/proxy for the first temperature sensor (e.g., where temperature measurements from the second temperature sensor may be used to replace temperature measurements from the first temperature sensor in a building model, etc.). In various embodiments, step 940 includes identifying a second data point sharing one or more characteristics with the first data point. For example, cloud building management platform 140 may identify a second data point having a tag indicating that a piece of equipment associated with the second data point is in the same building space as a first data point for which the second data point will act as a substitute for. In various embodiments, step 940 includes identifying a second data point having a higher confidence metric value than a confidence metric of the first data point. For example, cloud building management platform 140 may identify a second data point having an associated confidence metric value of 80% which is greater than the confidence metric value of 20% for a first data point.

At step 950, cloud building management platform 140 may generate and/or update at least one of a health metric describing a validity of information within a data analytics model or a confidence metric describing a likelihood that a tag of the unreliable first data point is valid based on determining that the first data point is unreliable. For example, cloud building management platform 140 may update a confidence metric of the first data point to indicate that the first data point is unreliable (e.g., has a low confidence metric value, etc.). At step 960, cloud building management platform 140 may identify one or more additional data points that may impact at least one of the health metric or the confidence metric. For example, cloud building management platform 140 may identify a data point relating to a temperature sensor in the same room as a thermostat and may retrieve a confidence metric associated with the data point. As another example, cloud building management platform 140 may identify a data point that has yet to be set up but would be expected to exist given context parameters associated with a space. For example, cloud building management platform 140 may identify a data point associated with a thermostat that cloud building management platform 140 would predict exists in a room but has not yet been set up (e.g., established within a building model, etc.).

At step 970, cloud building management platform 140 may generate a suggestion to obtain the one or more additional data points. For example, cloud building management platform 140 may generate a suggestion to integrate a security subsystem with a building model to increase a confidence associated with a number of tags related to occupancy sensors. In various embodiments, step 970 includes displaying a GUI to a user. For example, step 970 may include displaying a GUI to a user listing one or more additional data points that the user may configure (e.g., add to the building model, etc.) in order to increase a confidence metric value associated with a data point.

In some embodiments, at step 980, cloud building management platform 140 may suppress one or more alarms relating to the unreliable data point. For example, cloud building management platform 140 may automatically suppress a number of FDD alarms that were generated using sensor measurements obtained from the unreliable data point. In various embodiments, suppressing an alarm includes removing the alarm from a user interface. For example, cloud building management platform 140 may delete an alarm notification relating to a piece of equipment associated with the unreliable data point.

Referring now to FIGS. 10A-10B, method 1000 for identifying an anomaly and/or performing an action based at least in part on the identified anomaly is shown, according to an exemplary embodiment. In various embodiments, cloud building management platform 140 performs method 1000. At step 1010, cloud building management platform 140 may collect context information associated with a first data point of a first building. For example, cloud building management platform 140 may retrieve air flow measurements associated with an air-handling unit (AHU). As another example, cloud building management platform 140 may retrieve a temperature setpoint schedule associated with a space. In some embodiments, the context information includes historical operating data. For example, cloud building management platform 140 may retrieve damper settings for a HVAC system of a first type from a building model for a different building having the HVAC system of the first type. At step 1022, cloud building management platform 140 may execute a model on the context information to determine a future operational state associated with the first data point. For example, cloud building management platform 140 may execute a machine learning model to predict a number of temperature measurements associated with a space in the future based on the temperature setpoint schedule for the space.

At step 1024, cloud building management platform 140 may compare the context information to the future operational state. For example, cloud building management platform 140 may compare a measured temperature from a space to a predicted temperature generated by an Al model. In some embodiments, step 1024 includes determining an operation sequence for the first data point. For example, cloud building management platform 140 may determine that a smoke detector transitioned through state A, state B, and state C in sequence. At step 1026, cloud building management platform 140 may identify a drift condition associated with the first data point based on the comparison. For example, cloud building management platform 140 may identify a drift condition in response to determining that a measured temperature for a space deviates from a predicted temperature by a threshold amount (e.g., based on the comparison in step 1024, etc.). In various embodiments, the drift condition indicates a transition from an expected behavior to an unexpected behavior. In some embodiments, step 1026 includes identifying a drift condition based on a state transition sequence. For example, a building model may include a matrix of state transition sequences labeled as representing safe sequences and drift sequences and cloud building management platform 140 may identify a drift condition in response to identifying the first data point experiences one of the drift sequences.

Additionally or alternatively to steps 1022-1026, at step 1028, cloud building management platform 140 may retrieve historical data associated with at least one of the first data point or one or more related data points. For example, cloud building management platform 140 may retrieve historical security access requests associated with a data point representing an access control device (e.g., a smart door lock, a door controller, etc.). At step 1030, cloud building management platform 140 may compare the context information to the retrieved historical data. For example, cloud building management platform 140 may compare a proximity of employees workspaces to a control access device in a historical log to the proximity of employees workspaces to the control access device over the last week (e.g., to determine whether the group of individuals using a particular door has changed over time, etc.).

At step 1032, cloud building management platform 140 may identify an anomaly associated with the first data point based on the comparison. For example, cloud building management platform 140 may identify an anomaly in response to determining that a temperature of a space exceeds the historical temperature for the space by several standard deviations. In various embodiments, the anomaly relates to the first data point. For example the first data point may be related to a temperature sensor for a room and the first anomaly may be a high temperature anomaly.

Additionally or alternatively to step 1022-1026 and/or steps 1028-1032, at step 1034, cloud building management platform 140 may retrieve a second data point associated with an entity related to the first data point. For example, cloud building management platform 140 may retrieve a data point associated with a temperature sensor of a same type as a temperature sensor associated with a second data point. In various embodiments, the entity related to the first data point shares one or more characteristics (e.g., entity type, entity location, etc.) with an entity related to the second data point.

At step 1036, cloud building management platform 140 may compute a covariance between the first data point and the second data point. For example, cloud building management platform 140 may compute a covariance between temperature measurements of a first thermostat associated with the first data point and a temperature measurements of a second thermostat associated with the second data point. At step 1038, cloud building management platform 140 may identify a change in a trend associated with the first data point based on at least one of a change in the covariance between the first data point and the second data point or the context information. For example, cloud building management platform 140 may determine that two lighting controllers generally have the same schedule (e.g., there is a high covariance in the schedules of the two lighting controllers, etc.) and suddenly the schedules of the two lighting controllers differ dramatically and may identify the change as a change in a trend associated with a data point associated with one of the lighting controllers.

At step 1020, cloud building management platform 140 may identify an anomaly associated with the first data point. In various embodiments, step 1020 includes performing one of steps 1022-1038. Additionally or alternatively, step 1020 may include other processes as described herein. In various embodiments, the anomaly may include a drift condition and/or a change in a trend. At step 1040, cloud building management platform 140 may retrieve historical operating data from at least one of the first building or a second building having a threshold of shared characteristics with the first building. In various embodiments, step 1040 includes retrieving information from a building model (e.g., a building model such as a digital twin of the first building and/or the second building, etc.). For example, cloud building management platform 140 may retrieve historical carbon monoxide measurements from a building model associated with the second building.

At step 1050, cloud building management platform 140 may identify a cause of the anomaly based on the historical operating data. For example, cloud building management platform 140 may determine that a faulty HVAC damper is causing a high temperature anomaly associated with a space. In various embodiments, the cause includes at least one of an incorrect tag, a device fault, an unexpected configuration, or a change in at least one of the first building, a space of the first building, or a use of a space of the first building. For example, the cause may be a thermostat tagged as relating to a first room when in reality it is actually related with a second room. As another example, the cause may be a faulty piece of equipment. As another example, the cause may be an access control device configured to use an access whitelist (e.g., a database indicating who has access to spaces within a building, etc.) for a building other than the building the access control device is associated with (e.g., the wrong building, etc.). As another example, the cause may be a room of a building used to be used as a conference room but is now being used as a workspace.

In various embodiments, method 1000 includes performing one or more actions. For example, at step 1060, cloud building management platform 140 may generate a suggestion to change an attribute of a rule for triggering faults based on the cause. For example, cloud building management platform 140 may determine that an acceptable temperature range for a room was set too narrowly and may generate a suggestion to increase the range of acceptable temperatures for the space (e.g., to reduce future false alarms, etc.). At step 1070, cloud building management platform 140 may display at least one of the cause or the anomaly to a user. For example, cloud building management platform 140 may display a GUI to a user including the message: “Air filter needs replacing, please replace to reduce air particulate alarms.” At step 1080, cloud building management platform 140 may automatically update the incorrect tag or automatically update a device configuration of a device associated with the first data point to address the anomaly. For example, cloud building management platform 140 may update tag included in a building model to change a data point from being associated with a first space to being associated with a second space. At step 1090, cloud building management platform 140 may update a fault identification model using the context information based on the cause. For example, cloud building management platform 140 may update a FDD model to change one or more parameters associated with identifying an HVAC alarm based on determining the cause to be an incorrect lower temperature alarm threshold.

Referring now to FIG. 11, user interface 1100 for labeling a data point is shown, according to an exemplary embodiment. In various embodiments, cloud building management platform 140 displays user interface 1100 in response to receiving data representing one or more entities to be incorporated into a building model such as a digital twin. For example, cloud building management platform 140 may receive a table including strings and data and may perform semantic extraction on the strings to identify a building equipment identifier within a string, generate a data point corresponding to a piece of building equipment identified by the building equipment identifier, and map the data to the data point. In various embodiments, user interface 1100 includes data point 1110 and one or more parameters 1120. For example, user interface 1100 may include a data point such as an equipment identifier representing a piece of HVAC equipment. Parameters 1120 may correspond to one or more tags associated with data point 1110. For example, a data point associated with a thermostat may include a first parameter describing an entity type (e.g., thermostat, etc.), a second parameter describing a space within a building (e.g., room 2) and a third parameter describing a building (e.g., building 4E). In various embodiments, parameters 1120 correspond to one or more tags associated with data point 1110.

In various embodiments, user interface 1100 includes a recommendation for parameters 1120. For example, cloud building management platform 140 may execute a machine learning model on context information associated with data point 1110 to identify one or more suggested tags for data point 1110 and may display the one or more suggested tags as parameters 1120. Additionally or alternatively, user interface 1100 may facilitate a user to manually adjust parameters 1120. For example, a user may select a different parameter from a dropdown associated with parameters 1120. In various embodiments, user interface 1100 includes confidence metric 1130 describing a likelihood that parameters 1120 associated with data point 1110 are accurate. For example, cloud building management platform 140 may analyze context information associated with data point 1110 to generate confidence metric 1130. In various embodiments, confidence metric 1130 is updated based on the combination/selection of parameters 1120. In various embodiments, confidence metric 1130 is an interactive element. For example, a user may hover a cursor over confidence metric 1130 to view additional information associated with how the confidence metric was generated and/or how to increase a value of the confidence metric.

In various embodiments, user interface 1100 includes one or more options 1140. Options 1140 may facilitate a user to update a building model. For example, options 1140 may include a “Yes” option and/or a “No” option to tag data point 1110 using parameters 1120. In various embodiments, in response to a user selection of a “Yes” option, cloud building management platform 140 may update a building model to tag data point 1110 using parameters 1120. In various embodiments, in response to a user selection of a “No” option, cloud building management platform 140 may not update a building model. Additionally or alternatively, cloud building management platform 140 may update a confidence metric associated with data point 1110 and/or one or more tags associated with data point 1110 based on a user interaction with options 1140.

Referring now to FIG. 12, user interface 1200 for labeling a data point is shown, according to an exemplary embodiment. In various embodiments, cloud building management platform 140 displays user interface 1200 in response to receiving data representing one or more entities to be incorporated into a building model such as a digital twin. User interface 1200 is shown to include data point 1210 and one or more configurations 1220. Each of configurations 1220 may include one or more parameters 1224 and confidence metric 1226. In various embodiments, cloud building management platform 140 generates configurations 1220 based on a machine learning model. For example, cloud building management platform 140 may generate configurations 1220 representing a number of possible tags associated with data point 1210. In various embodiments, a user may select one of configurations 1220 to indicate that the user wishes to apply the selected configuration to data point 1210.

In various embodiments, parameters 1224 may correspond to one or more tags associated with data point 1210. For example, a data point associated with a thermostat may include a first parameter describing an entity type (e.g., thermostat, etc.), a second parameter describing a space within a building (e.g., room 2) and a third parameter describing a building (e.g., building 4E). In various embodiments, parameters 1224 are interactive elements. For example, a user may click on one of parameters 1224 to open a template associated with the selected parameter (e.g., a device template for a thermostat, etc.). Additionally or alternatively, hovering over parameters 1224 may display additional information associated with the parameter. In various embodiments, confidence metric 1226 describes a likelihood that each of configurations 1220 are accurate.

In various embodiments, user interface 1200 includes one or more options 1230. For example, options 1230 may include an “Accept” option, a “Reanalyze” option, and/or a “Skip” option. In various embodiments, cloud building management platform 140 performs one or more actions in response to a user selection of options 1230. For example, cloud building management platform 140 may update a building model to tag data point 1210 with one or more tags based on a selected configuration 1220 according to the associated parameters 1224. As another example, cloud building management platform 140 may update a machine learning model based on user feedback to increase an accuracy of future configuration suggestions. In some embodiments, a user selection of a “Reanalyze” option may cause cloud building management platform 140 to reanalyze information associated with data point 1210 (e.g., context information, etc.) to generate one or more new configurations 1220. In some embodiments, a user selection of a “Skip” option may cause user interface 1200 to skip configuration of the current data point 1210.

Referring now to FIG. 13, user interface 1300 for addressing a fault associated with an entity is shown, according to an exemplary embodiment. In various embodiments, cloud building management platform 140 generates user interface 1300. For example, cloud building management platform 140 may generate user interface 1300 in response to identifying an unusual number of faults associated with a piece of equipment. User interface 1300 is shown to include faults 1310, entity 1320, and options 1330-1360. In various embodiments, user interface 1300 presents a number of options for addressing faults associated with an entity. For example, an incorrectly configured data point may be causing a number of device faults and user interface 1300 may suggest a number of options to fix the incorrect configuration and/or remove the nuisance device faults. In various embodiments, faults 1310 describe one or more faults that are associated with entity 1320. In some embodiments, faults 1310 is an interactive element. For example, a user may select faults 1310 to display a faults user interface listing the faults associated with entity 1320. Entity 1320 may include an entity identifier and/or a data point associated with an entity such as a piece of building equipment. In various embodiments, entity 1320 is an interactive element. For example, a selection of entity 1320 may open a GUI map of a building and highlight a piece of equipment associated with entity 1320.

Options 1330-1360 may include one or more actions a user may take to resolve faults associated with entity 1320. For example, options 1330-1360 may include first action 1330 to clear/disable daisy-chained alarms, second action 1340 to update a configuration (e.g., of a data point, etc.), third option 1350 to verify tags (e.g., tags associated with a data point of entity 1320, etc.), and fourth option 1360 to update alarm rules (e.g., alarm rules associated with generating an alarm for entity 1320. In various embodiments, first action 1330 may disable one or more alarms and/or faults that are daisy-chained. For example, cloud building management platform 140 may disable (e.g., silence, etc.) a number of alarms that all stem from a single sensor measurement. Second action 1340 may cause cloud building management platform 140 to update a device configuration associated with entity 1320. For example, cloud building management platform 140 may update one or more tags associated with entity 1320 stored in a building model. Third action 1350 may verify one or more tags associated with entity 1320. For example, cloud building management platform 140 may execute a machine learning model on context information associated with entity 1320 to determine whether one or more tags associated with entity 1320 are valid. As another example, cloud building management platform 140 may dynamically control one or more environmental variables associated with entity 1320 to determine a validity of one or more tags associated with entity 1320. Fourth action 1360 may cause cloud building management platform 140 to update one or more alarm rules associated with generating alarms/faults for entity 1320 and/or entities of a similar type as entity 1320. For example, fourth action 1360 may cause cloud building management platform 140 to update a lower temperature threshold associated with an acceptable temperature range used for generating temperature faults for an HVAC system.

Referring now to FIG. 14, user interface 1400 for correcting a tag associated with an entity is shown, according to an exemplary embodiment. In various embodiments, cloud building management platform 140 generates user interface 1400. For example, cloud building management platform 140 may generate user interface 1400 in response to determining that a confidence metric associated with a data point falls below a threshold. In some embodiments, cloud building management platform continuously analyzes a building model to determine a health of one or more data points (e.g., a validity of tags associated with the data points, a validity of sensor measurements associated with the data points, etc.) and surfaces “unhealthy” data points to a user. For example, cloud building management platform 140 may determine that a tag relating to an entity type is likely incorrect (e.g., based on a low confidence metric associated with the tag, etc.) and may surface the tag and/or the data point to a user for review/correction.

User interface 1400 is shown to include entity 1410, tag 1420, parameters 1430-1436, and options 1440. In various embodiments, entity 1440 represents a data point or an entity such as a piece of building equipment represented within a building model such as a digital twin. In various embodiments, entity 1410 is an interactive element. For example, a user may select entity 1410 to display additional information associated with entity 1410 such as sensor data associated with a temperature sensor or a temperature setpoint schedule associated with a thermostat. In various embodiments, entity 1410 is represented using an identifier, however other representations are possible. In various embodiments, tag 1420 is a tag associated with a data point associated with entity 1410. For example, tag 1420 may describe a building equipment type tag associated with a data point representing a HVAC controller. In various embodiments, tag 1420 is identified as an incorrect tag.

Parameters 1430-1436 may include one or more options for different tags to replace tag 1420. In various embodiments, each of parameters 1430-1436 includes an associated confidence metric describing a likelihood that the particular tag is correct. In some embodiments, parameters 1430-1436 include a recommended parameter (e.g., roof top unit, etc.). In various embodiments, the recommended parameter includes a tag having the highest associated confidence metric value. In various embodiments, cloud building management platform 140 generates parameters 1430-1436 using a machine learning model. In some embodiments, a user may manually enter a parameter. For example, a user may select an option to manually enter a tag and may type in a tag for entity 1410 (e.g., parameter 1436, etc.). In various embodiments, selection of options 1440 cause cloud building management platform 140 to perform one or more actions. For example, options 1440 may include a first “Accept” option and a second “Ignore” option. In some embodiments, selection of an “Accept” option may cause cloud building management platform 140 to update one or more parameters (e.g., tags) associated with entity 1410 such as a tag of a data point related to entity 1410. In some embodiments, cloud building management platform 140 updates one or more models based on a user selection using user interface 1400. For example, cloud building management platform 140 may update a confidence metric associated with tag 1420 in response to a user selection to ignore the request to update tag 1420 (e.g., selection of “Ignore” option, etc.).

Referring now to FIG. 15, user interface 1500 for increasing a confidence associated with a tag is shown, according to an exemplary embodiment. In various embodiments, cloud building management platform 140 displays user interface 1500. For example, cloud building management platform 140 may display user interface 1500 in response to identifying a number of data points having low confidence metric values. In various embodiments, cloud building management platform 140 generates user interface 1500 based on an operation of a building. For example, cloud building management platform 140 may determine that, based on operational data from operation of a building, one or more tags associated with data points in a building model representing the building may be incorrect, and may display user interface 1500 in response.

In various embodiments, user interface 1500 includes entity 1510 and list 1520. Entity 1510 may identify an entity such as a building. In various embodiments, entity 1510 is an interactive element. For example, a user may select entity 1510 to display additional information associated with entity 1510. List 1520 may identify one or more data points that may have incorrect configurations such as incorrect tags. For example, cloud building management platform 140 may determine that, based on operation of entity 1510, a data point that was tagged as relating to a thermostat appears to instead relate to an AHU and may display the data point in list 1520. List 1520 may include elements 1522. Each of elements 1522 to relate to a data point. In various embodiments, elements 1522 include a dropdown option to display additional information associated with the element. Each of elements 1522 may include data point 1530, first parameter 1532, second parameter 1534, and/or confidence metric 1536. In some embodiments, elements 1522 include great, fewer, or a different combination of features (e.g., three parameters rather than two, etc.). In various embodiments, each parameter (e.g., first parameter 1532, second parameter 1534, etc.) relates to a different tag associated with data point 1530. For example, first parameter 1532 may relate to a tag describing an entity type of data point 1530.

In various embodiments, each of elements 1522 includes a parameter associated with a low confidence. For example, “TS10547” includes a “thermostat” parameter having a low confidence and “AHU10667” includes a “Room 91” parameter having a low confidence. In various embodiments, cloud building management platform 140 identifies parameters (e.g., tags, etc.) for review based on an associated confidence metric falling below a threshold value. In various embodiments, a user may select a dropdown option to view additional information associated with a parameter for review. For example, a user may select a dropdown option associated with “AHU10667” to display menu 1540. Menu 1540 may display second entity 1542 describing a space associated with entity 1510 for which additional data would improve a confidence metric value associated with one or more associated data points. For example, cloud building management platform 140 may be able to generate a more accurate model of a space if data from a HVAC controller serving the space became available and may generate a suggestion to configure the HVAC controller so that cloud building management platform 140 may use the data to verify a tag of a piece of equipment in the space, thereby increasing a confidence metric associated with the tag.

In various embodiments, menu 1540 includes data point list 1544. Data point list 1544 may include a number of data points that, if configured (e.g., if integrated into a building model, etc.), would increase an accuracy of a model used to verify a validity of data points and/or tags of the building model. Additionally or alternatively, menu 1540 may include validation data points 1546 describing one or more data points, that if validated (e.g., validating a configuration of the data points such as the tags of the data point, etc.), would increase a confidence associated with data point 1530. In various embodiments, validation data points 1546 are associated with data point 1530. For example, validation data points 1546 may be in a similar space as data point 1530 and/or share one or more characteristics with data point 1530. In various embodiments, menu 1540 includes options 1550 and 1560 for verifying validation data points 1546. For example, a user may select option 1550 to manually verify a data point of validation data points 1546. Additionally or alternatively, a user may select option 1560 to automatically verify a data point of validation data points 1546. For example, selection of option 1560 may cause cloud building management platform 140 to perform a dynamic adjustment process including controlling one or more environmental parameters, receiving one or more sensor measurements, and verifying a data point of validation data points 1546 based on the one or more sensor measurements.

Referring now to FIG. 16, user interface 1600 for tagging data is shown, according to an exemplary embodiment. In various embodiments, cloud building management platform 140 generates user interface 1600. User interface 1600 is shown to include data 1602, operation sequence 1610, parameter 1620, and options 1630. In various embodiments, user interface 1600 facilitates a user to determine a tag for a data point based on a selection of data (e.g., data 1602). For example, a user may select a portion of data, cloud building management platform 140 may identify one or more operation sequences associated with the data, and may generate a suggested tag associated with a data point related to the data based on the identified operation sequences. In various embodiments, cloud building management platform 140 executes a machine learning model to generate operation sequence 1610. In various embodiments, hovering a cursor over an element in operation sequence 1610 may highlight one or more data elements in data 1602 that are associated with the particular operation sequence element. For example, using a cursor to hover over an operation sequence element of “Set morning occupancy temperature” may highlight a command in data 1602 relating to changing a temperature setpoint of a space at 9:00 AM in the morning.

In various embodiments, operation sequence 1610 includes one or more elements, shown as elements 1612-1616. For example, operation sequence 1610 may include a first element “Set morning occupancy temperature,” a second element “Enter economizer mode due to no scheduled activity,” and a third element “Set out of office temperature.” In various embodiments, cloud building management platform 140 maps operation sequence 1610 to one or more parameters such as tags associated with a data point associated with data 1602. For example, cloud building management platform 140 may determine that typically operation sequences of a particular type are associated with thermostat entities and may generate a recommendation to create a data point from the data and tag the data point with a thermostat type tag. In various embodiments, user interface 1600 displays a recommended parameter (e.g., a tag, etc.) using parameter 1620. In various embodiments, parameter 1620 facilitates a user to change a tag. For example, a user may select a different entity type tag using a dropdown of parameter 1620. In various embodiments, options 1630 facilitate accepting or denying a suggested parameter. For example, a first option may include “Accept tag” and a second option may include “Skip.” In various embodiments, in response to a user selecting an “Accept tag” option, cloud building management platform 140 may update a building model to include a data point tagged with parameter 1620.

Referring now to FIG. 17, user interface 1700 for identifying a substitute/proxy for a data source is shown, according to an exemplary embodiment. In various embodiments, cloud building management platform 140 generates user interface 1700. For example, cloud building management platform 140 may generate user interface 1700 in response to identifying a data point as unreliable (e.g., based on a confidence metric associated with the unreliable data point, etc.). In various embodiments, user interface 1700 may facilitate a user to select a substitute for data within a building model. For example, a building model may use temperature measurements associated with a space to determine future operating parameters and a temperature sensor that supplies the temperature measurements may go offline (e.g., be unplugged, malfunction, etc.) and cloud building management platform 140 may generate user interface 1700 to facilitate a user to identify an alternate source of temperature measurements that the building model may use to determine the future operating parameters (e.g., another temperature sensor in the same room as the temperature sensor that went offline, etc.). In various embodiments, user interface 1700 includes GUI 1704 representing a space such as a 3-dimensional model of a room in a building. In various embodiments, user interface 1700 includes popup 1702 identifying entity 1710 that is unreliable or unavailable. In various embodiments, entity 1710 is identified on GUI 1704 as unreliable entity 1712. In various embodiments, user interface 1700 may facilitate identifying entities in a similar space as an unreliable or unavailable entity.

In various embodiments, cloud building management platform 140 generates recommended substitute 1720. For example, cloud building management platform 140 may identify an entity sharing one or more characteristics with entity 1710 (e.g., generates the same type of data, relates to the same type of entity, is located in the same space, etc.). In various embodiments, recommended substitute 1720 is identified on GUI 1704 as identified entity 1722. In various embodiments, a user may user cursor 1730 to select (e.g., by clicking, etc.) an entity within GUI 1704 to select the entity as a replacement for entity 1710.

Referring now to FIG. 18, user interface 1800 for performing an action related to missing data is shown, according to an exemplary embodiment. In various embodiments, cloud building management platform 140 generates user interface 1800. In various embodiments, user interface 1800 facilitates a user to perform one or more actions to fill-in missing data in a building model. For example, a building model may ingest setup data to generate one or more data points and the setup data may include a reference to timeseries sensor values associated with an entity but may be missing the sensor values and cloud building management platform 140 may facilitate a user to take one or more actions to resolve the missing data (e.g., fill in the missing data with modeled data, etc.), thereby improving the operation of the building model. In various embodiments, user interface 1800 includes point list 1810 and options 1860. In various embodiments, point list 1810 includes one or more points that are associated with missing data. For example, a data point may include a reference to timeseries sensor measurements associated with the data point and the timeseries sensor measurements may be missing values for a time period and point list 1810 may include a table listing the missing values and/or the data points associated with the missing values. In various embodiments, point list 1810 includes elements 1812 having checkbox 1820, point name 1830, point value 1840, and indicator 1850.

In various embodiments, each of elements 1812 relates to a data point having missing point values (e.g., sensor measurements, etc.). Checkbox 1820 may facilitate a user to select one or more of elements 1812. For example, a user may select a number of elements 1812 using checkboxes 1820 and may select one of options 1860 to perform an action on the selected elements 1812. In various embodiments, point name 1830 includes an identifier of a data point. For example, point name 1830 may include an identifier of a piece of equipment associated with a data point. In various embodiments, point value 1840 includes a point value (if available). For example, a data point may be missing an element in a series of sensor measurements and may display values for sensor measurements that are available but display a placeholder (e.g., “####,” etc.) for missing values. In some embodiments, point value 1840 displays the filled-in values. For example, a user may select for a data point to be filled-in using “Advanced data population” and point value 1840 may update to display the filled-in data generated using advanced data population. In various embodiments, indicator 1850 display additional information such as information regarding how cloud building management platform 140 generated data for point value 1840. In various embodiments, indicator 1850 is an interactive element.

In various embodiments, options 1860 are associated with a number of actions. For example, a first “Ignore” option may cause cloud building management platform 140 to ignore missing data associated with selected data points. As another example, a second “Advanced data population” option may cause cloud building management platform 140 to fill in missing data associated with selected data points using a machine learning model. As another example, a third “Static fill-in” option may cause cloud building management platform 140 to fill in missing data associated with selected data points using template data. Additionally or alternatively, cloud building management platform 140 may pull the data from a similar data point (e.g., a data point representing a similar entity, etc.). In some embodiments, cloud building management platform 140 may pull the data from historical operating information (e.g., may duplicate previous data associated with the data point to fill-in the missing portion, etc.). As another example, a fourth “Modeled” option may cause cloud building management platform 140 to fill in missing data associated with selected data points using modeled data. For example, cloud building management platform 140 may execute a machine learning model trained using historical data on any data that is available for the data point to infer the missing data.

Referring now to FIG. 19, user interface 1900 for visualizing data points is shown, according to an exemplary embodiment. In various embodiments, cloud building management platform 140 generates user interface 1900. For example, cloud building management platform 140 may generate user interface 1900 to facilitate a user to review data points updated using user interface 1800. In various embodiments, user interface 1900 includes list 1910. List 1910 may include elements 1920 displaying a data point and/or additional information such as associated sensor measurements. For example, list 1910 may include a number of elements 1920 including data points associated with a particular space. In some embodiments, user interface 1900 displays elements associated with generated data as identified elements 1930. For example, user interface 1900 may highlight a data point having filled-in data generated using user interface 1800. In various embodiments, each of elements 1920 includes data quality metric 1922. Data quality metric 1922 may describe a data quality associated with a data point related to element 1920. For example, data quality metric 1922 may be an aggregate of one or more confidence metric values associated with tags of a data point associated with element 1920.

Referring now to FIG. 20, system 2000 for dynamically verifying one or more data points in a space, shown as room 2002, is shown, according to an exemplary embodiment. In various embodiments, cloud building management platform 140 verifies one or more data points associated with room 2002. Additionally or alternatively, cloud building management platform 140 may auto-configure one or more data points associated with room 2002. For example, cloud building management platform 140 may analyze a data analytics model such as a graph data structure representing room 2002, identify information in the graph data structure that needs completing/updating, and perform one or more operations to derive information to at least partially complete and/or update the graph data structure. As a general example, cloud building management platform 140 may receive a data analytics model with a number of unlabeled sensors (e.g., sensors not associated with a specific space, etc.) and may operate one or more HVAC systems within a building while measuring operation of the number of unlabeled sensors to determine a location within the building that each of the number of unlabeled sensors is associated with. Room 2002 is shown to include thermostat 2004 and temperature sensor 2006. In some embodiments, room 2002 includes one or more users. In some embodiments, the one or more users having devices (e.g., mobile devices, etc.) that may be used to provide feedback to cloud building management platform 140.

At step 2010, cloud building management platform 140 may modify an operation of room 2002 and/or one or more entities (e.g., building assets, data points, etc.) associated with room 2002. For example, cloud building management platform 140 may modify operation of an HVAC system serving room 2002, may modify operation of one or more smart lights located in room 2002, and/or the like. In various embodiments, step 2010 modifies one or more environmental parameters associated with room 2002. For example, step 2010 may modify a temperature of room 2002, a lighting in room 2002, a sound level in room 2002, an asset within room 2002 (e.g., turning on/off a television, etc.), and/or the like.

At step 2020, cloud building management platform 140 may measure an effect of step 2010. Additionally or alternatively, cloud building management platform 140 may receive measurements from another system. Step 2020 may include receiving sensor information from one or more sensors. For example, step 2020 may include receiving a temperature measurement from at least one of thermostat 2004 and/or temperature sensor 2006.

At step 2030, cloud building management platform 140 may modify a data analytics model. For example, cloud building management platform 140 may modify a data point to replace a tag indicating that an entity is associated with “room 2” to indicate that the entity is associated with “room 3.” In various embodiments, step 2030 includes analyzing received data to determine relationships between various entities. For example, cloud building management platform 140 may determine that thermostat 2004 is located in room 2002 because thermostat 2004 measured a temperature increase corresponding to what would be expected based on operation of a HVAC system during step 2010. In some embodiments, step 2030 includes generating data to fill in gaps in an existing data analytics model (e.g., a digital representation of room 2002, etc.). For example, cloud building management platform 140 may generate relationship data (e.g., a tag, etc.) describing a location of a sensor for an existing sensor that is missing a location. In various embodiments, step 2030 includes analyzing data from various sources. For example, step 2030 may include analyzing user feedback from one or more users located in a room. For example, cloud building management platform 140 may operate a HVAC system that is not linked to which rooms it serves and may receive user feedback indicating that a specific room suddenly changed temperature (or became uncomfortable, etc.) and may determine that the HVAC system serves the specific room. As another example, cloud building management platform 140 may turn on/off a television that has not been associated with a specific space in a digital representation of a building and may receive user feedback that a television in a specific room turned on/off and may determine that the television is located in the specific room. In various embodiments, step 2030 includes generating one or more nodes and/or one or more edges.

Additionally or alternatively, step 2030 may include generating one or more data health metrics. For example, cloud building management platform 140 may generate a data health metric associated with thermostat 2004 that indicates that data from thermostat 2004 may not be valid. As a brief example, cloud building management platform 140 may determine that thermostat 2004 is supposedly located in room 2002, however upon changing a temperature of room 2002, cloud building management platform 140 may only observe a change in temperature measurements from temperature sensor 2006 (e.g., and/or one or more other temperature sensors, etc.) and may determine that thermostat 2004 may be malfunctioning (e.g., not producing reliable data) and may generate a health metric associated with thermostat 2004. Additionally or alternatively, cloud building management platform 140 may determine that thermostat 2004 is in fact not located in room 2002 (e.g., which would explain why thermostat 2004 did not register a change in temperature, etc.). In various embodiments, data health metrics may be used to reduce nuisance alarms and/or prevent alarm fatigue. For example, cloud building management platform 140 may suppress alarms associated with data points having a data health metric that indicates that the data may be unreliable.

Referring now to FIG. 21, entity graph 2100 is shown, according to an exemplary embodiment. In various embodiments, cloud building management platform 140 represents building 10 as entity graph 2100. For example, cloud building management platform 140 may generate a digital representation for a building and may use the digital representation as a data analytics model to perform various functions. In various embodiments, entity graph 2100 includes one or more data points having tags. For example, a data point may be represented as a node and a tag may be represented as an edge connecting two nodes. In brief overview, entity graphs such as entity graph 2100 are structured data stored in memory (e.g., a database, etc.). Entity graph 2100 may include digital twins. Digital twins may be digital representations of real world spaces, equipment, people, and/or events. In various embodiments, digital twins represent buildings, building equipment, people associated with buildings, and/or events associated with buildings (e.g., buildings 10, etc.). An entity graph may include nodes and edges, where each node of the entity graph represents an entity and each edge is directed (e.g., from a first node to a second node) and represents a relationship between entities (e.g., indicates that the entity represented by the first node has a particular relationship with the entity represented by the second node). For example, an entity graph may be used to represent a digital twin of a person.

Entities can be things and/or concepts related to spaces, people, and/or asset. For example, the entities could be “B7F4 North”, “Air Handling Unit,” and/or “meeting room.” The nodes can represent nouns while the edges can represent verbs. For example, the edges can be “isA,” “hasPart,” and/or “feeds.” In various embodiments, the edges represent relationships. While the nodes represent the building and its components, the edges describe how the building operates. The nodes and edges together create a digital twin of a particular building. In some embodiments, the entities include properties or attributes describing the entities (e.g., a thermostat may have a particular model number attribute). The components of the entity graph form large networks that encode semantic information for a building.

The entity graph is configured to enable flexible data modeling for advanced analytics, control, and/or artificial intelligence applications, in some embodiments. These applications may require, or benefit from information modeling including interconnected entities. Other data modeling techniques based on a table, a hierarchy, a document, and/or a relational database may not be applicable. The entity graph can be a foundational knowledge management layer to support other higher level applications, which can be, complex root cause, impact analysis, building powerful recommendation engines, product taxonomy information services, etc. Such a multilayer system, a system of system topologies, can benefit from an underlying entity graph.

The entity graph can be a data contextualization layer for all traditional and/or artificial intelligence applications. The entity graph can be configured to capture evidence that can be used to attribute the strengths of entity relationships within the entity graph, providing the applications which utilize the entity graph with context of the systems they are operating. Without context (e.g., who the user is, what the user is looking for, what the target of a user request is, e.g., find a meeting room, increase a temperature in my office) these applications may never reach their full potential. Furthermore, the entity graph provides a native data structure for constructing question and answer type systems, e.g., a chatbot, that can leverage and understand intent.

In various embodiments, the entity graph includes data from various sources. For example, the entity graph may include data associated with people, places, assets, and/or the like. In various embodiments, the data source(s) represent a heterogenous source data schema such as an open source common data model (e.g., a Brick Schema/extensions, etc.).

In various embodiments, entity graph includes digital twins and/or context information. A digital twin is a digital representation of spaces, assets, people, events, and/or anything associated with a building or operation thereof. In various embodiments, digital twins are modeled in the entity graph. In various embodiments, digital twins include an active compute process. For example, a digital twin may communicate with other digital twins to sense, predict and act. In various embodiments, digital twins are generated dynamically. For example, a digital twin corresponding to a conference room may update its status by looking at occupancy sensors or an electronic calendar (e.g., to turn its status “available” if there is no show, etc.). In various embodiments, digital twins and/or the entity graph include context information. Context information may include real-time data and a historical record of each system in the environment (e.g., campus, building, facility, space, etc.). Context information may be stored in the entity graph. In various embodiments, context information facilitates flexible data modeling for advanced analytics and Al application in scenarios that model highly interconnected entities.

The entity graph may not be a configuration database but may be a dynamic representation of a space, person, event, and the like. The entity graph can include operational data from entities which it represents, e.g., sensors, actuators, card access systems, occupancy of a particular space, thermodynamics of the space as a result of actuation, etc. The entity graph can be configured to continually, and/or periodically, ingest new data of the space and thus the entity graph can represent a near real-time status of cyber-physical entities and their inter-relationships. For this reason, artificial intelligence can be configured to introduce a virtual entity and new semantic relationships among entities, in some embodiments.

The entity graph is configured to facilitate adaptive controls, in some embodiments. The entity graph can be configured to adapt and learn over time. The entity graph can be configured to enable dynamic relationships between building information and other facility and enterprise systems to create new insights and drive new optimization capabilities for artificial intelligence systems. As relationships can be learned over time for the entity graph, the artificial intelligence systems and also learn overtime based on the entity graph. Entity graphs (e.g., space graphs, etc.) are described in greater detail with reference to U.S. patent application Ser. No. 16/260,078, filed on Jan. 28, 2019, the entire disclosure of which is incorporated by reference herein.

Entity graph 2100 includes entities 2110 (stored as nodes within entity graph 2100) describing spaces, equipment, events, and people (e.g., business employees, etc.). In various embodiments, entities 2110 are associated with or otherwise include agents (e.g., agents may be assigned to/associated with entities, etc.). Additionally or alternatively, agents may be represented as nodes in entity graph 2100 (e.g., agent entities, etc.). Furthermore, edges 2120 are shown between entities 2110 directionally describing relationships between two of entities 2110 (stored as edges within entity graph 2100). In various embodiments, cloud building management platform 140 may traverse entity graph 2100 to retrieve a description of what types of actions to take for a certain device, what the current status of a room is (e.g., occupied or unoccupied), etc.

As an example, entity graph 2100 illustrates a building called “Building 1.” Building 1 has a directional relationship to a floor called “Floor 1.” The relationship may be an edge “hasFloor” indicating that the building (e.g., the building represented by entity 2110) has a floor (e.g., the floor represented by entity 2110). Furthermore, a second edge “isPartOf” from Floor 1 to Building 1 indicates that the floor (e.g., the floor represented by entity 2110) is part of Building 1 (e.g., the building represented by entity 2110).

The apparatus may include special purpose logic circuitry, e.g., a field programmable gate array (FPGA) or an application specific integrated circuit (ASIC). The apparatus may also include, in addition to hardware, code that creates an execution environment for the computer program in question (e.g., code that constitutes processor firmware, a protocol stack, a database management system, an operating system, a cross-platform runtime environment, a virtual machine, or a combination of one or more of them). The apparatus and execution environment may realize various different computing model infrastructures, such as web services, distributed computing and grid computing infrastructures.

The systems and methods of the present disclosure may be completed by any computer program. A computer program (also known as a program, software, software application, script, or code) may be written in any form of programming language, including compiled or interpreted languages, declarative or procedural languages, and it may be deployed in any form, including as a stand-alone program or as a module, component, subroutine, object, or other unit suitable for use in a computing environment. A computer program may, but need not, correspond to a file in a file system. A program may be stored in a portion of a file that holds other programs or data (e.g., one or more scripts stored in a markup language document), in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files that store one or more modules, sub programs, or portions of code). A computer program may be deployed to be executed on one computer or on multiple computers that are located at one site or distributed across multiple sites and interconnected by a communication network.

The processes and logic flows described in this specification may be performed by one or more programmable processors executing one or more computer programs to perform actions by operating on input data and generating output. The processes and logic flows may also be performed by, and apparatus may also be implemented as, special purpose logic circuitry (e.g., an FPGA or an ASIC).

Processors suitable for the execution of a computer program include, by way of example, both general and special purpose microprocessors, and any one or more processors of any kind of digital computer. Generally, a processor will receive instructions and data from a read only memory or a random access memory or both. The essential elements of a computer are a processor for performing actions in accordance with instructions and one or more memory devices for storing instructions and data. Generally, a computer will also include, or be operatively coupled to receive data from or transfer data to, or both, one or more mass storage devices for storing data (e.g., magnetic, magneto-optical disks, or optical disks). However, a computer need not have such devices. Moreover, a computer may be embedded in another device (e.g., a mobile telephone, a personal digital assistant (PDA), a mobile audio or video player, a game console, a Global Positioning System (GPS) receiver, or a portable storage device (e.g., a universal serial bus (USB) flash drive), etc.). Devices suitable for storing computer program instructions and data include all forms of non-volatile memory, media and memory devices, including by way of example semiconductor memory devices (e.g., EPROM, EEPROM, and flash memory devices; magnetic disks, e.g., internal hard disks or removable disks; magneto-optical disks; and CD ROM and DVD-ROM disks). The processor and the memory may be supplemented by, or incorporated in, special purpose logic circuitry.

In various implementations, the steps and operations described herein may be performed on one processor or in a combination of two or more processors. For example, in some implementations, the various operations could be performed in a central server or set of central servers configured to receive data from one or more devices (e.g., edge computing devices/controllers) and perform the operations. In some implementations, the operations may be performed by one or more local controllers or computing devices (e.g., edge devices), such as controllers dedicated to and/or located within a particular building or portion of a building. In some implementations, the operations may be performed by a combination of one or more central or offsite computing devices/servers and one or more local controllers/computing devices. All such implementations are contemplated within the scope of the present disclosure. Further, unless otherwise indicated, when the present disclosure refers to one or more computer-readable storage media and/or one or more controllers, such computer-readable storage media and/or one or more controllers may be implemented as one or more central servers, one or more local controllers or computing devices (e.g., edge devices), any combination thereof, or any other combination of storage media and/or controllers regardless of the location of such devices.
